1
Q
Spatial Resolution
A
The smallest size of an object that can be picked out from its surronding objects or features
2
Q
Spectral Resolution
A
Number and dimension of specific wavelength interval of the EMR that a sensor is capable of measuring
3
Q
3 types of spectral resolution
A
- Panchromatic - one wide band encompassing a large spectral range
- Multispectral - Consists of narrower several bands of which two or three in visible and a few in NIR or MIR
- Hyperspectral - Consists of a large number of narrower bands spread across EMR
4
Q
Temporal resolution
A
The shortest period of time that a sensor will revisit/pass over the same spot on Earth’s surface
5
Q
Radiometric resolution
A
Number of unique values that can be recorded by a sensor when measuring reflected or emitted by EMR
